That's the problem I've had this season where I've created friends with some players on here to do some transfers, but we were unable to as we are not on the same server. Still, extra friends to give gifts to.
As for negotiations, I have bought about 4 players off them in the past two seasons (1 GK, who set an asking price but I stood my ground. He eventually sold him to me anyway, 1 DC/DR and 2 ST's) and sold none, either because I desperately need them or, most likely, the offer is so poor that I laugh at it then reject it.
